図２に示すように、挿入部１２の外周面には、ゴム等の弾性体から成るバルーン４２が装着される。バルーン４２は、両端部が絞られた略筒状に形成されており、挿入部１２を挿通させて所望の位置に配置した後に、バルーン４２の両端部を挿入部１２に固定することによって装着される。バルーン４２の端部の固定方法については後述する。   As shown in FIG. 2, a balloon 42 made of an elastic material such as rubber is attached to the outer peripheral surface of the insertion portion 12. The balloon 42 is formed in a substantially cylindrical shape with both ends narrowed, and is mounted by fixing the both ends of the balloon 42 to the insertion portion 12 after the insertion portion 12 is inserted and disposed at a desired position. The A method for fixing the end of the balloon 42 will be described later.

挿入部１２には、バルーン４２が取り付けられる範囲内に通気孔６２が形成されている。この通気孔６２は、図１の手元操作部１４の供給・吸引口４４に連通される。供給・吸引口４４にはチューブ６４が接続され、このチューブ６４がバルーン制御装置６６に接続される。バルーン制御装置６６は、チューブ６４を介してバルーン４２にエアを供給したり、エアを吸引したりするとともに、その際のエア圧を制御する装置であり、前面に設けられた操作ボタン６８によって操作される。なお、バルーン４２はエアを供給することによって略球状に膨張し、エアを吸引することによって挿入部１２の外表面に張り付くようになっている。   A vent hole 62 is formed in the insertion portion 12 within a range where the balloon 42 can be attached. The vent hole 62 communicates with the supply / suction port 44 of the hand operation unit 14 of FIG. A tube 64 is connected to the supply / suction port 44, and this tube 64 is connected to a balloon control device 66. The balloon control device 66 is a device that supplies air to the balloon 42 through the tube 64 and sucks air, and controls the air pressure at that time, and is operated by an operation button 68 provided on the front surface. Is done. The balloon 42 expands into a substantially spherical shape by supplying air, and sticks to the outer surface of the insertion portion 12 by sucking air.

次に、バルーン４２の端部の固定方法について図３〜図５に従って説明する。図３〜図５は、バルーン４２の装着手順を示す説明図であり、バルーン４２、係合部１００、押さえ環１１０は断面が示されている。   Next, a method for fixing the end of the balloon 42 will be described with reference to FIGS. 3-5 is explanatory drawing which shows the attachment procedure of the balloon 42, and the balloon 42, the engaging part 100, and the holding | suppressing ring 110 have shown the cross section.

これらの図に示すように、挿入部１２の外周面には一対の係合部１００、１００が設けられている。各係合部１００は突出して形成されており、円周方向に一周するように設けられている。また、係合部１００は、もう一方の係合部１００に対して反対側の側面が、挿入部１２の軸を中心とした円錐状に切り欠かれており、傾斜面１０２が形成されている。さらに、傾斜面１０２には嵌合溝１０４が円周方向に一周するように形成されており、この嵌合溝１０４に押さえ環１１０の突起１１４が嵌合するようになっている。   As shown in these drawings, a pair of engaging portions 100, 100 are provided on the outer peripheral surface of the insertion portion 12. Each engaging part 100 is formed so as to protrude, and is provided so as to go around in the circumferential direction. In addition, the engaging portion 100 is cut away in a conical shape with the axis of the insertion portion 12 as the center, and an inclined surface 102 is formed on the side surface opposite to the other engaging portion 100. . Further, a fitting groove 104 is formed on the inclined surface 102 so as to make one round in the circumferential direction, and the protrusion 114 of the pressing ring 110 is fitted into the fitting groove 104.

押さえ環１１０は、挿入部１２に着脱自在に取り付けられる部材であり、例えば図６に示すようにＣ状に形成され、二点鎖線で示す如く弾性変形させることによって挿入部１２に外周面側から装着できるようになっている。なお、押さえ環１１０の形状はＣ状に限定するものではなく、Ｏ状に形成されたものに切り込みを入れてもよい。   The retainer ring 110 is a member that is detachably attached to the insertion portion 12. For example, the retaining ring 110 is formed in a C shape as shown in FIG. 6, and is elastically deformed as indicated by a two-dot chain line to the insertion portion 12 from the outer peripheral surface side. It can be installed. Note that the shape of the presser ring 110 is not limited to the C shape, and a notch may be formed in the O ring shape.

また、押さえ環１１０は、図３に示すようにテーパ１１２を有し、このテーパ１１２は、係合部１００の傾斜面１０２と同じ角度で形成されている。テーパ１１２の先端には突起１１４が設けられており、この突起１１４が係合部１００の嵌合溝１０４に嵌め込まれる。これにより、押さえ環１１０が係合部１００に固定される。   Further, the holding ring 110 has a taper 112 as shown in FIG. 3, and the taper 112 is formed at the same angle as the inclined surface 102 of the engaging portion 100. A protrusion 114 is provided at the tip of the taper 112, and the protrusion 114 is fitted in the fitting groove 104 of the engaging portion 100. Thereby, the holding ring 110 is fixed to the engaging portion 100.

次に上記の如く構成された係合部１００と押さえ環１１０とでバルーン４２の端部を固定する場合、まず、図３に示すように、二つの押さえ環１１０、１１０を挿入部１２に取り付ける。その際、各押さえ環１１０のテーパ１１２がそれぞれ係合部１００の傾斜面１０２を向くようにする。   Next, when the end portion of the balloon 42 is fixed by the engaging portion 100 and the holding ring 110 configured as described above, first, the two holding rings 110 and 110 are attached to the insertion portion 12 as shown in FIG. . At that time, the taper 112 of each pressing ring 110 is made to face the inclined surface 102 of the engaging portion 100.

次に、先端側の係合部１００に、バルーン４２の端部を係合させる。すなわち、係合部１００の傾斜面１０２にバルーン４２の先端を当接させる。そして、この状態のまま、図４に示すように、先端側の押さえ環１１０を係合部１００側にスライドさせ、押さえ環１１０の突起１１４を係合部１００の嵌合溝１０４に嵌め込む。これにより、押さえ環１１０が係合部１００に固定されるとともに、バルーン４２の端部が押さえ環１１０のテーパ１１２と係合部１００の傾斜面１０２とによって挟圧され固定される。よって、バルーン４２の端部が挿入部１２に固定される。   Next, the end portion of the balloon 42 is engaged with the engaging portion 100 on the distal end side. That is, the tip of the balloon 42 is brought into contact with the inclined surface 102 of the engaging portion 100. Then, in this state, as shown in FIG. 4, the holding ring 110 on the distal end side is slid toward the engaging portion 100, and the protrusion 114 of the holding ring 110 is fitted into the fitting groove 104 of the engaging portion 100. As a result, the holding ring 110 is fixed to the engaging portion 100, and the end portion of the balloon 42 is clamped and fixed by the taper 112 of the holding ring 110 and the inclined surface 102 of the engaging portion 100. Therefore, the end portion of the balloon 42 is fixed to the insertion portion 12.

次に、固定されたバルーン４２の端部を基点として、バルーン４２を裏返す。これにより、図５に示すように、バルーン４２のもう一方の端部が基端側の係合部１００の位置に配置される。なお、バルーン４２に表裏がある場合には、予めバルーン４２を裏返しておき、このバルーン４２を先端側の係合部１００と押さえ環１１０とによって固定した後に、バルーン４２を裏返すことによって元の状態に戻すとよい。   Next, the balloon 42 is turned over with the end of the fixed balloon 42 as a base point. Accordingly, as shown in FIG. 5, the other end of the balloon 42 is disposed at the position of the engagement portion 100 on the proximal end side. When the balloon 42 has the front and back sides, the balloon 42 is turned over in advance, the balloon 42 is fixed by the engagement portion 100 and the holding ring 110 on the distal end side, and then the balloon 42 is turned over to return to the original state. Return to.

次にバルーン４２の基端側の端部を内側に折り返して、係合部１００の傾斜面１０２に係合させる。そして、基端側の押さえ環１１０を係合部１００側（すなわち、挿入部１２の先端側）にスライドさせ、押さえ環１１０の突起１１４を係合部１００の嵌合溝１０４に嵌め込む。これにより、押さえ環１１０が係合部１００に固定され、バルーン４２の端部が押さえ環１１０のテーパ１１２と係合部１００の傾斜面１０２とによって挟圧されて固定される。よって、バルーン４２の両方の端部が挿入部１２に固定される。   Next, the end portion on the proximal end side of the balloon 42 is folded inward and engaged with the inclined surface 102 of the engaging portion 100. Then, the holding ring 110 on the base end side is slid to the engaging portion 100 side (that is, the distal end side of the insertion portion 12), and the protrusion 114 of the holding ring 110 is fitted into the fitting groove 104 of the engaging portion 100. Thereby, the holding ring 110 is fixed to the engaging portion 100, and the end portion of the balloon 42 is clamped and fixed by the taper 112 of the holding ring 110 and the inclined surface 102 of the engaging portion 100. Accordingly, both end portions of the balloon 42 are fixed to the insertion portion 12.

このように本実施の形態によれば、押さえ環１１０を挿入部１２に沿ってスライドさせて係合部１００に嵌合させるだけで、バルーン４２の端部を固定することができる。よって、バルーン４２の装着作業を容易に行うことができる。   As described above, according to the present embodiment, the end portion of the balloon 42 can be fixed simply by sliding the pressing ring 110 along the insertion portion 12 and fitting it into the engaging portion 100. Therefore, the mounting operation of the balloon 42 can be easily performed.

また、本実施の形態によれば、バルーン４２の端部が折り返された状態で装着されるので、バルーン４２を強固に固定することができる。すなわち、端部を折り返さずに固定した場合よりも強固に固定することができる。   Further, according to the present embodiment, the balloon 42 can be firmly fixed because it is mounted with the end portion of the balloon 42 folded back. That is, it can fix more firmly than the case where it fixes without folding an edge part.

なお、上述した実施の形態は、バルーン４２の一方の端部を固定した後にバルーン４２を裏返して固定するようにしたが、図７に示すように、バルーン４２を予め丸めた状態にしておくと、バルーン４２の丸みを解くだけで、バルーン４２を挿入部１２に被せることができ、バルーン４２の装着作業を容易に行うことができる。   In the embodiment described above, the balloon 42 is turned over and fixed after fixing one end of the balloon 42. However, as shown in FIG. The balloon 42 can be put on the insertion portion 12 only by unraveling the roundness of the balloon 42, and the mounting operation of the balloon 42 can be easily performed.

また、上述した実施の形態は、バルーン４２の端部を折り返した状態で固定したが、これに限定するものではなく、例えば図８に示すようにバルーン４２の端部を折り返さずに固定するようにしてもよい。図８に示す係合部１２０にはテーパ１２２と突起１２４が設けられている。一方、図８の押さえ環１３０には、前記テーパ１２２に対応する形状の傾斜面１３２と、前記突起１２４が嵌合する嵌合溝１３４が形成されている。したがって、係合部１２０の突起１２４を押さえ環１３０の嵌合溝１３４に嵌合させることによって、係合部１２０のテーパ１２２と押さえ環１３０の傾斜面１３２とでバルーン４２の端部を挟圧して固定することができる。   In the above-described embodiment, the end of the balloon 42 is fixed in a folded state. However, the present invention is not limited to this. For example, as shown in FIG. 8, the end of the balloon 42 is fixed without being folded back. It may be. The engagement portion 120 shown in FIG. 8 is provided with a taper 122 and a protrusion 124. On the other hand, the holding ring 130 of FIG. 8 is formed with an inclined surface 132 having a shape corresponding to the taper 122 and a fitting groove 134 into which the protrusion 124 is fitted. Therefore, by fitting the protrusion 124 of the engaging portion 120 into the fitting groove 134 of the holding ring 130, the end portion of the balloon 42 is pinched by the taper 122 of the engaging portion 120 and the inclined surface 132 of the holding ring 130. Can be fixed.

また、上述した実施の形態は、係合部１００、１２０を挿入部１２と別部材として説明したが、挿入部１２の外皮部材と同材料によって一体的に形成してもよい。   Moreover, although embodiment mentioned above demonstrated engaging part 100,120 as the separate member from the insertion part 12, you may form integrally with the outer skin member of the insertion part 12 with the same material.

さらに、上述した実施の形態は、係合部１００、１２０を挿入部１２の外周面に突出形成したが、これに限定するものではなく、例えば図９に示すように、挿入部１２の外周面に溝１４０を形成することによって、挿入部１２に傾斜面１４２と嵌合溝１４４を形成してもよい。この場合、挿入部１２の溝１４０に押さえ環１１０を取り付けるようにすると、挿入部１２の外周面に突出部分がなくなり、挿入部１２の体腔内への挿入を容易に行うことができる。   Further, in the above-described embodiment, the engaging portions 100 and 120 are formed so as to protrude from the outer peripheral surface of the insertion portion 12, but the present invention is not limited to this. For example, as shown in FIG. The inclined surface 142 and the fitting groove 144 may be formed in the insertion portion 12 by forming the groove 140 in the insertion portion 12. In this case, if the holding ring 110 is attached to the groove 140 of the insertion portion 12, there is no protruding portion on the outer peripheral surface of the insertion portion 12, and the insertion portion 12 can be easily inserted into the body cavity.

また、図４〜図７に示した係合部１００及び押さえ環１１０の外周縁部、図８に示した係合部１２０及び押さえ環１３０の外周縁部は、円弧状の面取り部が形成されて滑らかになっており、体腔内への挿入に支障のないようになっている。   4-7, the outer peripheral edge portions of the engaging portion 100 and the presser ring 110 and the outer peripheral edge portions of the engaging portion 120 and the presser ring 130 shown in FIG. 8 are formed with arc-shaped chamfered portions. It is smooth so that it does not hinder insertion into the body cavity.

なお、本発明は、バルーン４２を内視鏡１０の挿入部１２に装着する場合だけでなく、挿入部１２の挿入を補助する挿入補助具（いわゆるオーバーチューブ、スライディングチューブ等とよばれるもの）やプローブにバルーンを装着する場合にも適用することができる。   In the present invention, not only when the balloon 42 is attached to the insertion portion 12 of the endoscope 10, but also an insertion aid (so-called overtube, sliding tube or the like) that assists the insertion of the insertion portion 12; The present invention can also be applied when a balloon is attached to the probe.
